SPECIFICATION forming part of Letters Patent N o. 771,707, dated October4, 1904. Application iiled October 21, 1903. Serial No. 177,906. (Nomodel.)

To LLZZ whom t may concern:

Be it known that I, JOSEPH BURGER, a citizen of the United States,residing at Winfield, in the county of Cowley and State of Kansas, haveinvented an Incubator, of which the following is a full and completespecification.

This invention relates to incubators; and the objects of the inventionare to provide an incubator which shall be simple and compact inconstruction, effective in use, and shall provide for quickly andconveniently turning the eggs when required.

These and other objects and advantages are attained by a peculiarconstruction of incubator wherein the trays which hold the eggsduringincubation are radially supported from a horizontal shaft and thesaid revoluble sets of trays mounted in a cylindrical casing having awater-belt and heating device therefor, by which latter the eggs may bemaintained at the proper temperature.

The following specification enters into a detail description of myinvention, reference being had to the accompanying drawings, and what Iclaim as novel, and desire to protect by Letters Patent, is morespecifically set forth in the appended claim.

In the drawings, Figure l is a side elevation showing my incubatorarranged for use. Fig. 2 is a longitudinal vertical sectional view. Fig.3 is an end view. Fig. 4 is a transverse vertical sectional view. F ig.5 is a detail view of the trays.

Similar letters of reference indicate similar parts in all the views ofthe drawings.

In carrying out my invention I employ, in the first place, a cylindricalcasing A, suitably supported upon legs aand composed, preferably, of awooden body provided in front with an opening a', having a hinged doora2. Around this casing, lengthwise of is a water-pipe B, having afeed-opening i7), and that part of this pipe which extends down one endof the cylinder or casing is enlarged, as at to accommodate a verticaliiuec, extending through the center of said enlarged portion andpreferably funnelshaped, as

shown. At the lower end of this iiue is placed a lamp,

as D, which serves to heat the water in the the same,

pipe and by which heated water the proper temperature of the eggs ismaintained. An opening or vent fis located in the upper part of thecasing, and in this opening may be placed a thermometer to ascertain thetemperature of the air in said casing. It will be seen, therefore, thathot water is employed as the direct heating medium and that the pipewhich contains the water extends lengthwise of the casing and around thesame to heat all parts thereof evenly, also that the said water-pipebeing continuous a circulation is kept up in the same.

In the casing hereinbefore described the eggs are arranged in a peculiarmanner. Extending' longitudinally through the center of the casing A andbearing in the ends thereof is a horizontal shaft E, to which aresecured, so as to radiate therefrom, a series of trays F, the bottom,top, and inner end of 'which are preferably made of wire-netting, sothat the air can circulate freely around the eggs which are placedtherein. These trays are comparatively wide and are therefore providedwith longitudinal partitions f, so that the egg-compartments so formedextend the full length of the tray and the eggs are placed thereinlengthwise in a row. The top f2 of each tray is hinged at its inner end.and at its outer end is provided with a spring-catchf', by which it isheld closed. By arranging the egg-trays in the casing upon a horizontalshaft, as herein shown and described, all the trays may be turnedsimultaneously, and by giving the shaft a half-turn all the eggs will beturned over. The shaft is extended beyond one end of the casing andprovided with a crankhandle.

In iilling the incubator the trays are successively brought to theopening a and filled, and after all the trays are filled, or as many asdesired, the door a2 is closed, the waterpipe B is filled with water,and a lamp is then placed under the iiue O. rIhe hot water circulatingaround the casing will supply the heat to maintain the eggs at theproper temperature, and the eggs may be turned when desired by simplyturning the crank e.

By locating the hot-water pipe around the casing and longitudinallythereof a more uniform temperature can be maintained with a IOOcomparatively small flame to the lamp, and

necessary ventilation is secured by opening' the front door This door ispreferably covered with glass, so that the condition of the eggs can beviewed without opening said door, and as the chicks are hatched they areremoved 'from the trays.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

ln an incubator, the combination, of a cylindrical casing, a hot-Waterpipe extending around the same longitudinally and centrally and providedwith an enlarged portion or section down one end of the casing, saidenlarged portion of the pipe being Wider at the lower end andtaperedupward, a flue extending' up Ward through said enlargement of thepipe, and a lamp placed under said flue; together with a horizontalshaft mounted in the casing and having a crank-handle at one end beyondsaid casing, and egg-trays attached to said shaft and projectingradially therefrom, said trays being made up of Wire-netting and havinga hinged top held closed by a springcatch; the casing being provided infront with a hinged door as herein shown and described.

1n testimonywhereof l have signed my name to this specification in thepresence of two subscribing witnesses.
